THREAD-BOARDCLEANING APPARATUS.

To all whom it may concern:

Be it known that I, HOWARD D. CoLMAN, a citizen ofthe United States, residing at Rockford, in the county of lVinnebago and State of Illinois, have invented certain newl and useful Improvements in rlhread-Board- Cleaning Apparatus, of which the following is a specification.

This invention relates to improvements in the class of apparatus illustrated in application Serial No. 562,431, filed May 20, 1910, by Howard D. Colman and Burt A. Peter- T he object of this invention is to simplify and otherwise improve the means for driving and reversing the cable which operates the cleaning devices, and to improve the means for guiding the cable.

In the accompanying drawings, Figure 1 is a fragmental plan view of a spinning frame provided with apparatus embodying the features of my invention. Fig. 2 is a transverse vertical sectional view taken in the plane of dotted line 2 2 of Fig. 1. Fig. 3 is a fragmental side elevation of the cabledriving and reversing mechanism. Fig. 4c is a sectional. view illustrating a portion of said mechanism in a different position than that represented in Fig. 3. Fig. 5 is a top plan 4View of the parts seen in Fig. 3. Fig. 6 is a detail view illustrating the reversing member and the means for operating said member.` Fig. 7 is a fragmental sectional view through the reversing member and an auxiliary means for moving said `member. Fig. 8 is a view looking from the right-hand side of Fig. 5; Fig. 9 is a section on line 9 9 of Figr;

` `In the drawings d arethe drawing rolls, b the thread boards, c the thread guides hinged to said thread boards, and d the usual pigtails on the thread guides.

The cleaningapparatus comprises two devices 1 of any suitable character, arranged to be reciprocated upon the thread boards `and the thread guides of the spinning frame, one cleaning device being provided for each side ofthe frame. Said devices are attached to anendless cable2 which is moved first in onedirection and then in the other to traverse the cleaning devices from one end to the other of the thread boards. At the corners of the spinning frame are provided brackets 3 towhich are attached cable guides Specification of Letters Patent.

extending entirely around the cable so as to obviate any possibility of the cable leaving its guides.` Herein I have shown thecable guides as consisting of short sections of tube 4L brazed, soldered or otherwise secured to the brackets 3, the tubes being bent so as to guide the cable around the corners. Intermediate the guides at one end of the spinning frame is a bracket 5 supporting a sleeve or short tube 6 through which the cable runs.

The mechanism for driving the cable and for reversing its direction of movement when the cleaning devices have traveled from one end of the thread boards to the other, is `supported upon and at one end of the spinning frame. Said mechanism comprises a base plate 7 to which are secured two upwardly extending brackets 8 and 9. In these brackets is mounted a shaft 10 having fixed to one of its ends a sheave 11 having therein a plurality of annular grooves to receive the cable 2. Proper tension is maintained in the cable by extending a loop of the cable downward from the sheave 11 through openings 12, and supporting in said loop a weighted take-up sheave 13. The means for rotating the shaft 10 comprises a wheel 14 fixed upon said shaft and having square peripheral teeth 15.`

These teeth are engaged by a pawl pivoted upon an arm 16, said arm being fast to a sleeve 17 surrounding the shaft 10. The sleeve 17 is mounted ina bearing opening in the bracket 8. The arm 16 is swung by means of an arm 18 secured to the sleeve `17 and connected by a link 19 to a crank arm 20 fixed to one of the drawing rolls a. The pawl consists of two oppositely extending fingers 21 and 22, each adapted to engage the teeth 15. A spring 23 fixed to the arm 16 at 24. and to a finger 25 upon the pawl at 26 tends t0 hold either finger' in operative position.

The means for shifting the pawl to bring p its fingers 21 and 22 alternately into operative `position comprises a three-arm member 27 fixed to a sleeve 2S (Fig. 7 which is loosely mounted on a pin 29 projecting from the bracket 9. The middle arm 30 of the reversing `member 27 is arranged for engagement by a studBl fixed to a spur gear wheel 32 which `is loosely mounted upon the shaft 10. Said spur gear meshes with a pinion 33 formed uponor otherwise suitably secured to a shaft 341, to which shaft is fixed a spur gear 35 meshing with a pinion 36 formed in or attached to the shaft 10. rlhe arms 37 and 38 of the reversing member 27 have angular ends adapted alternately to engage a projection 39 (Fig. 8) upon the finger 25. il member 40 having notches 41 and 42 therein is formed upon the sleeve 28. These notches are adapted to receive a wedge-shape tooth 43 Yformed upon a lever 44 pivoted at 45 and acted upon by a tension spring 4G.

Assuming the parts to be in the position shown in Figs. 3 and 6, the operation 1s as follows: Each rotation of the crank 20 produces an oscillation ot the arm 16` each such oscillation causing a feeding movement and a restoring movement of the pawl Vfinger i1. The intermittent movement thus imparted to the toothed wheel 14 causes the stud 31 to swing the arm 30 until the point of thc tooth 43 has lett the notch 41 and is about to enter the notch 42, when the pressure ot said tooth causes the reversing member 27 to swing into the position shown in Fig. 4. The arm 37 of the reversing member is thereby placed inthe path ot the projection 39 upon the awl so that continuedv movement ot the arm 1G to the left (Fig. 4) causes the pivot of the pawl to pass to the opposite side of a straight line joining the points Q4 and 26, whereupon the spring 23 turns the pawl to throw the finger into operative position. The direction of rotation oi the toothed wheel 14 is thereby reversed, with a consequent change in the direction oi' travel ot the cleaning devices 1. The length of movement of the stud 31 is so proportioned to the length of the thread-boards that the reversing member 27 is swung from one of its positions to the other when the cleaning devices reach the end of the thread boards.

I claim as my invention:
